We study the two-Higgs-doublet model with type-II seesaw mechanism. In view of constraints from Higgs data, we consider aligned scheme and its effects on muon anomalous magnetic dipole moment, $a_{\mu}$, including both one-loop two-loop Barr-Zee type diagrams. Thanks to a sizable trilinear scalar coupling, diagrams mediated by triplet fields have dominant effect $a_{\mu}$. particular, unlike us...
